The invention discloses a limiting device of a crane trolley. The limiting device comprises a sliding rail, baffles, rubber rods, springs, rubber pads, anti-sliding blocks and the trolley, wherein thetwo baffles are fixed to the left end and the right end of the upper plane of the sliding rail through bolts; the two baffles are provided with the same speed reduction devices; each speed reductiondevice comprises the corresponding baffle, the corresponding rubber rod, the corresponding spring and the corresponding rubber pad; the three rubber rods are fixed to the center of each baffle throughbolts and form an equilateral triangle; each rubber rod is wound with the corresponding spring; the right end of each spring is welded to the corresponding baffle; the left end of each spring is fixedly provided with the corresponding rubber pad through a bolt; the rubber pads and the rubber rods form the same triangle; the two anti-sliding blocks are embedded in the upper plane of the sliding rail and located at the lower ends of the two speed reduction devices correspondingly; the upper planes of the anti-sliding blocks and the upper plane of the sliding rail are located on the same horizontal line; the trolley is placed in the middle of the sliding rail; and the two rubber pads are fixed to the side faces of the left end and the right end of the trolley through bolts. The limiting device has the beneficial effects of being stable, safe, and small in impact force and the like.
